Well, at this point you are just toxic just by thinking about Zoro approaching anywhere close to Kaido...
Relax, it is Oda's story, there are two strongest Emperors in Wano and you think that one of the strongest fighters in the arc wont have a go against them? You will be very disappointed when it happens, I guess.
Unless your headcanon pictures Luffy taking out both of them, then I get it.
